IMPROVEMENT IN EXTENSIO N T ABLES. M

Specification forming part of Letters Patent No. 122,800, dated January16, 1872.

' To all whom it may concern:

Be it known that I, JOHN M BLAISDELL, of Sanbornton, in the county ofBelknap and State of New Hampshire, have invented a new and usefulImprovement in Extension Tables, of which the following is aspecification:

My invention consists in the combination, with an extension table, of asliding reccp tacle or draw for the extra leaves of the same, whichreceptacle is so arranged under the extension slides as to be entirelyhid from view when the table is closed and unextended, but which can,when the table is to be extended, slide out sidewise, to allow the extraleaves to be taken from the same for use.

In the accompanying drawing, Figure l is a side view of my improvedextension table when closed. Fig. 2 is a side view of the same whenpartially opened, showing the receptacle for the extra leaves inposition before being drawn out. Fig. 3 is a central cross-sectionthrough the receptacle before the latter is drawn out and Fig. 4 is asimilar section, the receptacle being drawn out to its full length.

To the under side of the central sectional extension slides A, (on whichthe other slides close up,) and at each end of the same, are securedcross-pieces B, provided with grooves g on their inner faces, in whichslide tongues i, formed on the outside of the upper portion of thereceptacle 0, which is thus suspended from the pieces B, while it issupported by a leg, D, secured on the under side of the'receptacle O andmoving with the same. This leg is made in two pieces, the short lowerone 01 being provided with an upwardly-extendin g stem, which fits in acorresponding opening in the upper portion D of the leg, a springbearing against the lower portion d, keeping the latter extendeddownwardly from the former in constant contact with the floor. The twoparts D and cl may be held to each other by a pin and slot, or any otherwell-known and suitable device. On the under side, and at each end ofone of the pieces B, or both of them, I secure stops 1), and on thecorresponding side or sides of the receptacle 0 a horizontal projection,0, so that the latter, striking against one or the other of the projeotions b, will limit tacle be a complete box, with ends and bottom, orconsist only of two sides, connected to each other by cross-pieces attheir bottom, near their ends and center, as shown in the drawing. Theshape of the box will, of course, have to depend upon the shape andconstruction of the leaves. I have shown the leaves as folding in twoways, two of the same folding at their ends only, and the other in thecenter only. In this case I attach to the inside of one of the sides ofthe receptacle 0, near each end, a vertical cleat, which does not extendentirely to the top of the side of the receptacle, and

against which the pins which secure the leaves to each other and to thetop of the table abut when the leaves are placed in the receptacle, thuspreventing the leaves from sliding out either way and necessitatingtheir being lifted out.

The operation of my device is very easily understood. The table beingclosed, and it being desired to extend it, the two parts of the tableare moved from each other a sufiicient distance to allow the receptacle0, after opening the button 6, to be slid out. The desired number ofleaves having been taken out, the receptacle is pushed in and locked inplace by the button 0, and the leaves arranged upon the table. Inreducing the table the leaves are folded before being placed into thereceptacle.

When the table is closed, and all the leaves in the receptacle, thelatter is entirely hid from view. The leg D, being arranged in twoparts, does not interfere with the movement of the receptacle, but itmoves easily over any inequalities of the floor or other smallobstructions.

By placing the receptacle 0 under the extension slides, and removing theleaves therefrom endwise, instead of up through the extension slides, Iam enabled to arrange the extension slides in an; desired manner, and inthe best way to strengthen the table.

Having thus described my invention, I clairn--- 1. In combination withan extension table, thelaterally-sliding receptacle 0 for the leaves,arranged substantially as described.

2. In combination with the laterally-sliding receptacle 0 for theleaves, arranged substantially as described, the adjustable leg D 01,substantially as described.
